CronSparkSchedule HTTP jobs. Monitor everything. Get notified when it breaks.
Cron jobs, heartbeat monitors, status pages, and alerts in one place. Set it up once — we call it, watch it, and tell you the moment something's wrong.
POST /api/v1/sync
Every 5 minutes
Heartbeat: nightly-backup
Expected every 24h
PUT /reports/daily
Daily at midnight
Everything you need to run jobs with confidence
CronSpark bundles cron scheduling, uptime monitoring, status pages, and alerting — the tools you'd normally stitch together from two or three separate services.
Cron & Interval Scheduling
Standard cron expressions with a visual builder and human-readable preview, or simple fixed intervals — plus one-click crontab import to bring your existing schedules over in seconds.
Heartbeat Monitors
Dead man's switch monitoring for background jobs and scripts — if a check-in doesn't arrive on time, we tell you immediately.
Multi-Channel Alerts
Email, Discord, Slack, and Telegram notifications the moment something fails, with snooze and maintenance windows to avoid noise.
Public Status Pages
Branded status pages with incident timelines and maintenance announcements, plus optional email subscriptions so your users get notified the moment something changes.
Job Chaining & Pattern Matching
Trigger a follow-up job only on success, and validate responses against a regex pattern — not just an HTTP status code.
Execution Logs & Trends
Every run logged with status, response code, and duration. Visualize trends over time and export everything as CSV or JSON.
REST API & API Keys
Manage jobs and monitors programmatically with a full REST API and scoped API keys — automate your automation.
Secure by Default
Built-in SSRF protection blocks requests to private networks, every job runs with a 30s timeout, failed jobs retry automatically with backoff, and outgoing webhooks are signed with HMAC-SHA256 so you can verify they came from us.
Team Collaboration
Invite teammates with admin or read-only roles, track every change in a shared activity log, and add extra seats on demand for $2/mo each.
CLI
Manage jobs straight from your terminal with the CronSpark CLI — create, edit, and trigger jobs without leaving your shell.
Status Badges
Embed a live status badge for any job in your README or internal dashboard — shows passing, failing, timeout, or paused at a glance.
Tags, Timezones & Templating
Organize jobs with tags, schedule each one in its own timezone, and inject dynamic variables like {{timestamp}} or {{job_id}} into request headers and bodies.
Three steps to peace of mind
1. Add your URL
Provide the endpoint you want us to trigger.
2. Set a schedule
Define the timing using standard cron syntax.
3. We handle the rest
Relax while we execute and monitor your jobs.
Simple, predictable pricing
Focus on building, not managing cron infrastructure.

Why teams switch to CronSpark
